IMPROVEMENT IN SPINNING-MACHINES.

Specification forming part of' Letters Patent No. 43,846, dated August 16, 1864.

frame and parts ofa throstle-spin ning machine with our improvements applied thereto. Fig. 4 is an end view of our invention and the mechanism with which it is directly connected.

Our improvement has reference to that mechanism of a throstle-spinning machine by which the vertical movements ofthe spindles are produced and regulated in order that the yarns, while being spun, may be wound in a proper manner on their several bobbins.

Our improvement also has special reference yto the invention for which Letters Patent N o.

9,283 were granted on the 28th day of September, A. D. 1852, to Charles H. Hunt, and is a new-or improved let ofi'77 or escapement mechanism to. be used in connection with a reciprocating mangle wheel and the gear of Ithe shaft with which the curved links or A goose-necks 7 employed in operating the spindle-rails are applied.

In the said drawings we have not represented any spindles or fliers or their equivalents, but have exhibited the spindle-rails as used in ordinary throstle-frames, it being understood that when in use each of the rails is to support a series ofspindles to work in the usual manner with a series of iiiers.

In Figs. 1, 2, and 3 of the drawings, -A A denote the stationary iiierrails 5 B B, the spindle-rails, and E E the guide-rods of the said spindle-rails. Each of the rails B B is suspended from two sheaves, al a, upheld by. arms b b, by means of two chains or cords, c c, which pass partially around the sheaves and thence forward toward and are respectively fastened to two curved links or goosenecks, d d, which are connected to the main shaft F of the frame G, such shaft being arranged as shown in the drawings. These curved links or goose-necks are applied to the shaft F and are intended for the same purpose as those described and represented in the said patent of the said Hunt. The shaft, like its counterpart in the said Hunts machinery, has a large gear, H, iixed on it coneentrically. We also employ, as does the said Hunt, a mangle-wheel, I, which we snpport on a stationary journal, e, arranged as shown in the drawings. This mangle-wheel, formed in side view, as shown in Fig. 4, has a pinion, lc, for operating it, the said pinion beng fixed on a vibratory shaft, l, supported by wo bearings, m a. The first of these bearings-viz., m--shonld be so applied to its supporting-rail o as to be capable of being turned a little horizontally. The other bearing-viz., n-is so adapted to its rail p as to be capable of being moved in directions longitudinal thereotlthat is to say, it is inserted in a slot, q, within which it can slide from end to end of the slot. 0n rotating the shaft l the pinion 7c will impart to the mangle-wheel a reciprocating rotary motion-that is to say, the mangle-wheel will be caused to make very nearly an'entire revolution in one direction,

after which it will revolve a like distance in the opposite direction.

Aiiixed tothe side of the mangle-wheel, and so as to turn with it on the journal e, is a pinion, r, which engages with the curved rack s of one arm of a sectoral lever, c, which has the shaft F for a fulcrum, the shaft going through the lever. The other arm of the lever Gis properly formed with a bearing, t, for the support of a short shaft, u, which has a ratchet or cscapement wheel, o, at one end, and a pinion, fw, fixed on its other end. The pinion w engages with the large gear H, hereinbefore mentioned.

An escapement or rocker lever D, formed as shown in the drawings, is supported by and so as to be capable of freely turning on a fulcrum, extended from the lever C. This escapement lever D has two pallets or arms, y z, which operate with the teeth of the wheel o. The third arm, a', ofthe lever D is weighted or heavier than the pallets and operates to press one of them-viz., the unhooked pallet yclose up to the periphery of the ratchet.

Through an arm, b', projecting from the rail p, a screw or tripper, c', is screwed and so that its point may be in the path of movement of the tail or arm c of the eseapementlever D.

For revolving the shaftl there may be a pulley fixed on its'outer end, such pulley to receive rotary motion from a belt duly put in movement.

An adjustable stop, d', projects from that face of the gear H which is next to the sectoral 4lever U, there being a similar stop, e', projecting from the latter, the same being as shown in Figs. 5 and 6, and 7 and 8, Fig. 5 being a side view, and Fig. 6 an edge view,`ot the gear H, while Fig. 7 is aninner side View, and Fig. 8 is an edge view, of the sectoral lever.

By the reciprocating rotary motions of the manglewheel corresponding reciprocating vibratory motions will be imparted to the sectoral lever C. While the pallet y of the escapement-lever may be in engagement with the escapement-wheel or ratchet e, the shaft u will be prevented from being revolved. Consequently the sectoral lever, by pressing the pinion w against oneof the teeth of the gear H, will cause the shaft F to revolve, the are of its revolution being coincident with that of the sectoral lever, with the exception that, in consequence of the tail a of the escapementlever D being carried in contact with the tripper c', such escapement-lever will be so turned as not only to force its arm y out of action with the esca-pementwheel, but the hooked arm ,z into action with it. In the interval between these movements of the two arms y and z the escapementwheel will be free to revolve, and will do so until stopped by the arm z. The weight of the spindle-rails acting on the shaft F, through the cords c c and the goose-necks d d, tends to revolve the shaft and allow the spindle-rails to descend; but while the pallet y may be in engagement with the escapement-wheel the spindle-rails will not be checked from descending through the action of gravity, operatin g independently of the mechanism by which the shaft F is revolved for the purpose of raising the spindlerails.

In the process of laying or windin g the yarn on each bobbin the shaft F is not only to have imparted to it a regular reciprocating rotary motion, such as will raise and lower the spindle-rails, but at the termination of y each elevation or raising o f the spindle-rails the shaft F is to be let off or turned a little, so as to unwind the goosenecks from it, in order to allow each of the spindle-rails to drop a short distance to effect the building up of the yarn on the bobbin. Thus the machinery for regulating the movements ot' the spindlerails notonly causes these movements to be such as to lay the yarn on the spool or bobbin in regular layers, but causes the rails to be dropped a little distance prior to each wind or winding of the yarn, in order that each wind may rise a little higher on the bobbin than did the preceding wind.

The stops d e serve to enable the sectoral' lever to be brought into its proper position relatively to the rest of the mechanism preparatory to the laying of the yarn on the bobbin. By taking hold of a wheel, A', fixed on one end of the shaft F, and turning it, the said'shaft may be revolved, so as not only to wind the goose-necks and their connections up thereon and raise the spindlerails up to their highest positions, but bring the 'two studs d e into contact and thereby adjust the let-off mechanism for operation.

Our invention ispositive iu its action, and not attended with what mechanics term backlash. It is simple, easily kept in order, and can be readily repaired when defective.

We do not claim a combination composed of an escapement mechanism and a reciprocating rotary manglewheel, the same being used in a spinning machine, and for automatically operating its spindle-rail in such manner as not only to impart to it the necessary movements for effecting each Wind or layer of yarn on the bobbin, but those by which each successive layer is caused to rise a little above that immediately preceding it, as a combination of this nature is found described in the said patent of the said Hunt; but

We claim as our invention or im provement l. The combinationapplied to the reciproltriangle-wheel I, the shaft F, the pinion r, the

wheel c, the shaft u, pinion uf, the tripper c',

the spindle-rail and its connections with the shaft F,the purpose of such stops being as hereinbefore described.
